saurn,

Ошибочка:

Код:

procedure TimerProc(hwnd: HWND; uMsg: UINT; idEvent: UINT_PTR; dwTime: DWORD);
begin
    WizardForm.NextButton.Enabled := not IsProcessRunning('calc.exe');
end;

Код:

procedure TimerProc(hwnd: HWND; uMsg: UINT; idEvent: UINT_PTR; dwTime: DWORD);
begin
    WizardForm.NextButton.Enabled := not IsProcessRunning(''WorldOfTanks.exe');
end;

лучше тогда так:

Код:

#define KillExe "WorldOfTanks.exe"
